- Item #20931
- Thomsenolite, Siderite, Sphalerite, Ralstonite
- 12.4x9.0x7.5
cm

Largest Crystal Size: 6mm
-
$260.00
- Ivigtut Deposit
- Ivittuut, Arsuk Fjord
Greenland
- There are cavities all over this specimen that are lined with superb, elongated, terminated thomsenolite crystals. Of course as is usually the case, the thomsenolite is white but has a light coating of iron oxide that give the specimen its classic look. Matrix appears to me massive thomsenolite with a few small siderite and sphalerite crystals embedded in it. As well, there are small cube-octahedral ralstonite crystals on the thomsenolite crystals, inside the vugs. We don't seem much of this material around any more!
